Silvertel has developed analog telecom interface modules that are easy to use, small in size and yet require very few extra components. Available in single in line (SIL) or dual in line (DIL) packages.

SLIC module Silvertel's Subscriber Line Interface Circuit (SLIC) modules can be used for analog telephone line interface applications, enabling signals to be transmitted and received from a telephone line, feed power to the line and to monitor the line condition. The modules are ideal for use in ISDN Terminal Adaptors, Internet Telephony (VoIP), Computer Telephony Integration (CTI), Wireless Local Loop (WLL), Fixed Cellular Terminals (FCT), Fixed Wireless Terminals (FWT) and Small Office Home Office (SOHO) applications.

PSTN module Silvertels' PSTN interfaces are also known as Trunk Interfaces, Foreign exchange Office (FXO) circuits, Data Access Arrangements (DAA) and Central Office Interface Circuits (COIC). Silver Telecom PSTN modules are suitable for a wide range of applications, meeting the requirements of CTR21, FCC Pt.68, UL60950, AS NZ3260 and AS ACIF S043. The ability to provide a programmable d.c. mask, line and network impedances gives our PSTN modules the flexibility to be used in any market. On-Hook reception allows support for Caller Line ID and by using transformer isolation this provides high common-mode rejection for use in ungrounded systems as well.

SLICS

Ag1171 is a low cost single channel SLIC with a fully integrated DC-DC converter to generate all necessary battery and ringing voltages. The module only requires a single supply from +3.3V to +5V. Ag1171 is suitable for low line count, short loop applications, such as Wireless Local Loop Terminals (WLL), Fixed Cellular Terminals (FCT), Fixed Wireless Terminals (FWT) and Internet Telephony (VoIP).

The world's first +3.3V only ringing SLIC. Also available as a +5V version, Ag1170 has a built in DC-DC converter to generate all of the tricky telecom and ringing voltages on board - all from a single +3.3V (or +5V) supply. Ag1170 is available in SIL or DIL formats, ideal for VoiP applications.

A low cost long loop SLIC, in a space-saving single-in-line package, requiring very few external components. Suitable for high line applications such as Central Office, Digital Loop Carrier and Pair Gain Systems.

PSTN Interfaces, Trunk Interfaces, FXO, DAAs or COICs

A low cost PSTN Interface in a SIL package. Boasting many features including a basic barrier on-chip. Can be used in systems without a ground, or in applications where common mode interference is very high. Can also be operated at +3.3V or +5V supply.

A highly integrated COIC in a DIL or SIL package. Boasting many features including a basic barrier on-chip. Can be used in systems without a ground, or in applications where common mode interference is very high. Can also be operated at +3.3V or +5V supply.
